Time the record covers
At least 195 million years on record.
The record covers at least 449.9 Mya to 254.14 Mya. No occurrence read is dated outside 452.8 Mya to 251.902 Mya.
509 occurrences of Rhombopora on record, most of them in the Carboniferous. Bar height is expected occurrences, not a count: each fossil is spread across the span it is dated to, so a tall narrow bar means tight dating and a low wide one means loose.
When
509 occurrences- Ordovicianunder 1%
- Silurianunder 1%
- Devonian6%
- Carboniferous57%
- Permian37%
These are dates about fossils, not the animal: the record can only begin after it arose and end before it died out, so either end may reach further. Shares are expected occurrences: a fossil dated to a span is counted partly in each period it straddles. More on what this infers.

The Paleobiology Database records 456 sites for Rhombopora, and this reads 240 of them. The number is how many of those sites it was catalogued from too. The 24 sharing the most are listed.
This is not a list of everything alive at the time. It is only what has come out of the same ground as this animal and been written down.
